Yes, it is possible to stroll to an island. Cana Island, with its historic lighthouse facilities, is open to the public seasonally. Please call or visit the Web site below for details. Walk across the rock causeway from the Door County mainland to the island. Step inside the keeper's house where, beginning in 1869, the first of a number of lighthouse keepers tended to the light which guided sailors and protected them from the dangerous shoals extending out from the island into Lake Michigan. Take a look in the oil house, where fuel for the light was stored prior to days when electricity came to the island. The buildings and grounds have been maintained by the Door County Maritime Museum for nearly 30 years while the United State Coast Guard continues to oversee the tower with its stunning third order Fresnel lens and light. A Wisconsin's Maritime Trails Sign featuring the shipwreck Frank O'Connor is also on the lighthouse grounds. The O'Conner, an 1892 bulk carrier, lies 2.6 miles northeast of the island in 60 feet of water. The O'Conner sank in 1919 and is over 300 feet long, making it one of the largest wooden vessels ever built.
